Abstract

(57) [Abstract] [Purpose] An object of the present invention is to provide a method for easily performing manual paper feeding in a printer device and the like, which does not affect the already-installed paper such as dust. [Structure] The discharge roller and the auxiliary roller are configured to be releasable, and manual paper is inserted into the gap. In addition, the paper ejection tray is arranged so that it can be pulled out, and by manually placing the manual paper on it, the paper can be positioned and fed. [Effect] The tray of the paper ejection section is a drawer, and you only need to put the manual paper on it, so you can easily operate it, and since it does not touch the automatic paper feed section, you can prevent the intrusion of dust etc. .

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper manual feed mechanism of a printing device used for office equipment or the like.

[0002]

[Prior Art]

 A conventional manual feed mechanism will be briefly described with reference to FIG. A printer device such as a thermal dye sublimation transfer method using a special coated paper is provided with an automatic paper feeding mechanism so that the paper can be supplied without touching the user's hand as much as possible.

When printing with the hot-melt ink transfer method with such an apparatus, it is necessary to use a paper different from the above-mentioned dedicated coated paper.

In this case, after the manual paper 30 is placed on the dedicated paper 6 of the automatic paper feed case 10, the paper feed roller 28 moves in the direction of arrow K and is conveyed to the printing portion of the thermal head 1 and the platen roller 2. It was done and was printing.

[0005]

[Problems to be solved by the device]

 As described above, in the conventional manual paper feed mechanism, when manually feeding, the automatic paper feed case is pulled out from the main body of the apparatus, the paper to be printed is placed on the automatic paper feed case and returned to the inside of the apparatus to perform printing. That was necessary.

Further, there is a problem in that the special paper is contaminated by dust from the outside due to the attachment / detachment operation of the automatic paper feed case, which affects the print quality.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is provided with a tray that can be pulled out and a release roller release mechanism in the paper discharge unit, and is configured to perform manual paper feed from that location.

[0008]

【Example】

 Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. The printing operation during automatic paper feeding will be described with reference to FIG. The special paper 6 set in the automatic paper feed case 10 is pushed toward the paper feed roller 28 by the hopper spring 11. When the printing operation is started, the paper feed roller 28a moves 28b (in the direction of arrow K) onto the special paper 6 and then rotates. By this rotation operation, the special paper 6 is sent to the printing section one by one.

The dedicated paper 6 fed from the automatic paper feed case 10 passes through the paper guide 29, is conveyed between the thermal head 1 and the platen roller 2, and is superposed on the ink ribbon 5. The ink ribbon 5 is supplied from the ribbon supply bobbin 8 and, after passing over the thermal head 1, is wound onto the ribbon winding bobbin 9 by being driven by the ribbon feed roller 7.

The special paper 6 that has passed over the thermal head 1 is arranged between the capstan roller 3 and the pinch roller 4 and reciprocates.

The portion of the special paper 6 on which printing has been completed passes through the paper guide 29 and is guided to the paper discharge roller 17 and the auxiliary roller 15.

The delivery roller 17 is driven by the delivery roller pulley 24, the drive belt 26, and the motor pulley 25 to drive the sheet delivery motor 27, and rotates together with the capstan roller 3 when the sheet is delivered.

As shown in FIG. 1, the auxiliary roller 15 is supported by an auxiliary roller arm 13, and the auxiliary roller arm 13 is configured to be rotatable about an auxiliary roller arm shaft 23 as a fulcrum.

An auxiliary roller tension shaft 21 is provided on the side of the auxiliary roller arm 13 opposite to the auxiliary roller 15 with the auxiliary roller arm shaft 23 interposed therebetween. The auxiliary roller spring 12 is provided at the center of the auxiliary roller tension shaft 21. The auxiliary roller 15 is pressed against the discharge roller 17 side by the auxiliary roller arm 13.

Auxiliary roller releasing cams 14 are provided on the auxiliary roller arms 13 and are connected by an auxiliary roller releasing shaft 22. An auxiliary roller release lever 20 is provided at one end of the auxiliary roller release shaft 22 and is rotatable in the arrow E direction. The auxiliary roller release cam 14 described above rotates in conjunction with the rotation operation of the auxiliary roller release lever 20.

The auxiliary roller arm 13 is pushed down by the rotation of the auxiliary roller release cam 14 in the direction of the arrow M. At this time, the auxiliary roller arm 13 is rotated about the auxiliary roller arm shaft 23 in the arrow F direction to release the auxiliary roller 15 pressed against the paper discharge roller 17 in the arrow C direction.

By releasing the rollers of the paper discharge unit by the above-described operation, a gap for inserting a sheet is made and the manual sheet 16 is inserted.

A paper discharge tray 18 is provided in a portion where the paper is discharged from the paper discharge roller 17, and can be pulled out in the direction of arrow A via a trail 19. The paper output tray 18 is provided with a positioning wall 31 so that the paper can be accurately positioned with respect to the apparatus when a paper is placed thereon. The paper discharge tray 18 is pulled out, the manually fed paper 16a is placed on the paper discharge tray 18b, the paper discharge tray 18 is set again in the apparatus, and printing is performed. A handle 32 is provided on the discharge tray 18 so that it can be easily pulled out.

[0019]

[Effect of the device]

 According to the above invention, since the paper is manually fed from the paper discharging portion, the automatic paper feeding section is not operated. Therefore, since the automatic paper feed case is not attached or detached and the paper is not replaced, it is possible to obtain high-quality images without the intrusion of dust, etc. The effect is that it can be done easily and accurately.
